I want make an email script for users to be able to send me messages
and i getting Mail delivery failed: returning message to sender

this is the script

<li><form name="mail" method="POST"  
<li><input type="text" name="to"  
<li><input type="text" name="Message"  
<li><input type="text" name="from"  
<li><input type="text" name="cc"  
<li><input type="submit" name="submit"  

and the send_main.php

  $to = $_POST['to'] ;      
  $message = $_POST['Message'] ;  
  $from = $_POST['from'];  
  $cc = $_POST['cc'];  
  $headers =  "From: ".$_POST['from']."\r\n" .  
"CC: ".$_POST['cc'];  
  mail( $to, "Mail", $message, $headers);  

Do you know what the returned message states? I see you have specified a From address in the script so the bounce would be returned there.

thanks man i did it. Thanks
